AUTOMATIC PUMPING SYSTEM.

Specification of Letters Patent.

Patented Nov. 16, 1909.

Application filed September 29, 1908. Serial No. 455,266.

tion and particularly to an automatic pumping system.

An object of this invention is to provide novel means for lifting and distributing liquid preferably water, the said apparatus being operated hydraulically and having means for filling receptacles which, owing to their weight, descend and operate pumping mechanism for lifting and distributing water.

A further object of this invention is to provide novel means for temporarily supporting the receptacles in an elevated position, means being also provided for tripping the supporting mechanism when the receptacle has been filled to a predetermined degree.

A further object of the invention is to provide novel valve operating mechanism under the influence of the receptacle supporting means whereby when the said receptacle is brought into operative relation with a tank the said valve is open to permit the liquid to flow from the tank into the receptacle.

A still further object of this invention is to provide a water lifting device operated through the agencies just described, the said lifting device having suitable valves for controlling the flow of the liquid therethrough.

\Vith the foregoing and other objects in view, the invention consistsin the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views, in which Figure 1, illustrates the apparatus by a top plan view; Fig. 2, illustrates the said apparatus in side elevation; Fig. 3, illustrates an end view thereof; Fig. i, is a plan view on an enlarged scale showing a portion of the apparatus; Fig. 5, illustrates a side elevation of the parts shown in Fig. 4;; Fig. 6, illustrates an enlarged detail View of the end of the apparatus shown in Fig. 5; Fig. 7, illustrates an enlarged detail view of the receptacle supporting means; Fig. 8, is an enlarged detail view illustrating the same in side elevation; and Fig. 9, illustrates a sectional view of the base of the water distributing members.

In these drawings A, denotes an elevated tank supported by a standard B, the said standard rising from a base tank C,having a normal water line on the dotted line D, the said base tank 0, being provided with a dram pipe d, for the discharge of the water in the event of its rising above the normal water line D.

The tank C, is provided with two pump cylinders E, having the piston rods F, rising therefrom and connected to a walking beam Gr, pivotally mounted on the standard B. As the said walking beam G operates the pump rods F, F, are alternately reciprocated and the pumps are thereby operated to draw water from the tank G, and force it through the pipes H, H, to the base I, of the distributing apparatus. The base is provided with ports J, J, and said ports are controlled by the valves K, K, each of which has a stem 70 depending into its port in order that the said valve may be guided to its seat L, after the liquid has passed through the port.

The base I, is provided with a discharge pipe M, having a port N, in its base which communicates with the ports of the base I. The pipe M, has a valve seat 0, for the valve P, and the said valve has a stem Q, for guiding it with relation to its seat. As the pump pistons are operated, liquid is forced through the ports of the base and the valves are alternately seated and unseated to permit water to flow therethrough and the pressure attained by the pumps is sutlicient to cause the liquid to rise in the pipe M to be distributed to any suitable service system or through the end 0, of the pipe.

As a means for operating the walking beam G, I employ the receptacles R, having bails 1', supported from the hangers S, which hangers are pivotally connected to the walking beam. The receptacles are provided with valves T, guarding the openings 16, in the bottom of said receptacles and each valve T, is provided with a valve stem U, which projects through the opening 15, and is provided with an enlarged head a. In the bottom of the tank C, I provide blocks V, against which the heads of the valve stems abut as the receptacles descend and when the ends of the valve stems contact the said blocks, the valves are unseated from the bot tom of the receptacles and the contents of the said receptacles is free to be discharged i therefrom into the base tank Q. As each I receptacle receives a predetermined supply I l o n I of liquid 1t descends and the receptacle on c the opposite end is elevated into position to receive a supply of liquid while the contents of the one which has descended is being discharged.

As a means for supplying the liquid to the elevated receptacles, the elevated tank A, is provided with discharge openings (1, a, con trolled by valves it being understood that these parts are duplicated at each end of the tank. Each valve "W, is provided with a valve stem 10, to which is attached a pivotally mounted arm X, which arm has a projection X extending transversely beyond the side of be elevated when the end of the walking beam G, rises. As a means for moving the pivoted arm X, and the valve with it, the walking beam G, has a bracket Y, projecting above its upper surface and as the walking beam is elevated, the end of the bracket Y, contacts the pivoted arm X, and causes the valve to be unseated. The contents of the elevated tank A, is thereby allowed to How into the receptacle R, until said receptacle is filled to a predetermined degree.

The ends of the walking beam are held elevated by means of latches, one at each end of the tank A, and as these parts are practically duplicates, only the apparatus at one end Will be described. The latch comprises a reciprocating member Z, suitably guided and having pivotally connected thereto, a bolt Z, provided with an anti-friction roller Z which is adapted to operate in conjunction with an angular bracket Z near the end of the walking beam. As the bracket Z is elevated, it comes in contact with the bolt and lifts it slightly to cause it to move the tank and is adapted to out of its path of travel after which said bolt drops into a horizontal position again where it is held by the spring Z The angular end of the bracket then rests on the bolt as the receptacle R, is being filled and while the opposite receptacle is discharging its contents. lVhen a predetermined amount of liquid has passed into the receptacle R, the float R, is elevated and the top red B on the float rises to contact the block Z, on the right-angled lever Z, said right-angled lever being pivoted at the point Z hen the outer end of the lever is thus elevated, its inner end swings the intermediate lever Z on its pivot Z", and as the said intermediate ever Z is connected to the member Z the the valve causes it to again seat to close the opening in the bottom of the receptacle and the elevated receptacle may then be filled in like manner.

As a means for cushioning the movement of the walking beam, spring-held buffers 13, are attached to the outer surface of the tank and as tl e ends of the walking beam comact the buffers, the springs will yield suliieiently to prevent undue shock and vibration during the operation of the pumping apparatus.

As it will be observed that the pumps are operated simultaneously with the walkil'ig ea1n, it follows that the liquid which has been delivered to the base tank C, by the receptacles will be pumped out of the said base tank C, through the pipe M. Through this mechanism the pump will be automatically controlled and operated so long as the supply of liquid is delivered to the tank A, through a pipe or other conductor X As a means for preventing the overflow of the elevated tank A, a drain pipe X is pro-, vided to carry ofi the excess supply of water, and in order to prevent splashing the machinery, I connect the pipe through the side wall of the elevated tank A, and have it extend downwardly in order that it will dis-, charge into the base tank C, and as heretofore explained, the base tank O, is provided with a drain pipe D, so that the excess water, or liquid is conveyed away from the apparatus.

I claim:
